摘要
A three-dimensional X-ray diffraction microscopy (3DXRD) experiment has been performed on 50% cold-rolled aluminium AA1050 to investigate in situ the growth rate of individual recrystallizing grains at 310 degrees C and 325 degrees C. Growth rates and apparent activation energies are determined for seven individual grains. It is found that the recrystallization kinetics of the individual grains show large deviations, in good agreement with earlier 3DXRD experiments. It is also found that the recrystallization kinetics at 50% deformation vary less in time than what has been found in similar studies of 90% deformed aluminium.
